sesses a large capacity for the circulationv of i the cooling water, andeffects a thorough cooling of' such water. The invention furthercomprises novel and eflicient means, for removing any damaged section ofthe radiator without.distal-tong the remaining sec tions.

In the accompanying drawing:

Figure l, is a perspective view of an automobile radiator embodying myinvention',

Fig. 3, a horizontal section on line 3-3 Fig. 2 with the tlanges of thefront plates partly broke-1i away;

A Fig. 4,' a vertical cross section on line 4 4 Fiv. 3;

Fig. 5, a perspective view of oneof the de tachable cooling units, and

Fig. 6 an enlarged. cross section through The radiator, as shown, isofthe socalled torpedo type, being composed of two wings, that join at anacute angle. It comprises essentiall a pair 'of converging upper watercham rs 2 having o en bottoms, and a pair of corresponding y arrangedlower water chambers 3 having open. tops. At Vthe rear ends-the twochambers 2, 3 of each wing abut against a common back plate A, while attheir forward en'ds all the four chambers abut against a common uprightmember 5, the whole forming a frame.

Above this frame there is mounted a hood 6 l that spans both of thewings and is furnished with a filling nozzle 7.

Between the water chambers 2, 3 of each wing are interposed ai,plurality of cooling units each composed o a front late 8, a rearplate 9, and a plurality of tu es 10, set into said plates, and adaptedfor the passage of thoP cooling, air. The front plates 8 areconsiderably longer than the rear plates 9 (Fig. 5), and abut'at theirforward edges against the upright member 5, while the rear plates 9 ofone wing will at their forward edges abut against t e forward 'edges ofthe other wing. In this way, there will ,be formed at the nose of theapparatus, an additional upright water chamber 11, which is devoid ofi111 air tubes so as to retain its maximum capacity. This upright waterchamber 'l1 communicates at its u per end with the converging front endsof t e u per water chambers 2, at its lower end wit the converging frontends of the lower water chambers 3 and at its inner end with the severall units' constituting the air-cooled members 8, 9, 10. The hot waterfrom the motor cylinders is admitted to the top of chamber 11 or toeither one of' the upper chambers 2)& y inlet nozzle 12, and iswithdrawn from either one of the lower chambers 3 by an outlet nozzle13. In this way a circulation will take place, part of the water passingthrough, to t e the cooling units to be here subjected action of the airpipes, while part ofthe i 'water will flow through the u right chamber1l, to be here cooled by the raft or cooling air currents induced bythemotion of machine through space, the water being also4 free to flowdirectly between the upright chamber and the cooling units.

y Thus it will be seen that the capacity of the radiator is largerelatively to its size,l while all of the' circulating water will bethoroughlycooled.

The several cooling units are made removable from each other so that'anyone that may have become defective through collision or otherwise, maybe replaced without disf turbing the remaining perfect unita To thiseffect, the front plates 8, are provided with horizontal rearwardlyextending flan s 14, while the rear plates 9 are provide with horizontalforwardly extending flanges 15, the flan es 14 with the constructionshown, protruding beyond the ianges 15.'

lVhen the several units are fitted within the frame, the two flanges 14of two adjoining units will overlie each other, as will 'also theflanges 15. By now soldering the overlying flanges together, the unitswill be connected in a water tight manner,'the flanges furn'ishin anample surface for the rece tion of t e so1der.When any one of e units isto be replaced, thesolder is removed by the application of a solderingliron.

Though I have shown a. number of coolin units to be incorporated intoeach wing o the radiator, e sin 1e unit may be so emplayed, Whenever t eremovable feature of the cooling members is not desired.

I claim: l

A n automobile radiator composed of u pair of converging upper waterchambersfa:

p air of 'convergm ower water chambers, and cooling mem ers' interposedbetween said chambers, each cooling member being .formed of a rearplate, a front plate proj ecting a distance beyond the rear plate, and aplurality of air tubes set into the plates the forwardly projecting endsof the front pietes forming an u right water chamber at the 'nose-ofthera infor.
